The LMF100 consists of two independent general-purpose high-performance switched-capacitor filters. With an external clock and 2 to 4 resistors, a variety of second- and first-order filtering functions enable each filter block. Each block has 3 outputs. An output can be configured to perform an all-pass, high-pass, or notch function. The other two outputs perform bandpass and lowpass functions. The center frequency of each filter is tuned by using an external clock or a combination of clock and resistivity. A fourth-order biquadratic function that enables a single LMF100. Higher-order filters are implemented by simply cascading additional software packages, and all classical filters (such as Butterworth, Bessel, Ellipse, and Chebyshev can be implemented).
In the process of high-performance analog silicon gate CMOS from National Semiconductor, LMCMOS™LMF100 is fabricated. This enables the production of a very low offset, high-frequency filter building block. The LMF100 is pin-compatible with the industry standard MF10, but offers dramatically improved performance.
